nessus_tcp_scanner.c (Nessus 2.2.10) error in gcc 2.96
|

Dear Nessus Team,
I am writing you because I have found an error in the
"nessus_tcp_scanner.c" plugin.
I have found this error on the following Red Hat Linux 7.3 distribution:
Enviroment:
-----------
[root [at] Isaia nessus_tcp_scanner]gcc --version
2.96
[root [at] Isaia nessus_tcp_scanner]# cat /etc/issue
Red Hat Linux release 7.3 (Valhalla)
[root [at] Isaia nessus_tcp_scanner]# uname -a
Linux Isaias 2.4.18-3 #1 Thu Apr 18 07:37:53 EDT 2002 i686 unknown
[root [at] Isaia nessus_tcp_scanner]# ldconfig -v | grep ssl
libssl.so.2 -> libssl.so.0.9.6b
This is a brief of what appeared on my screen

I have solved this issue on my own, changing a few coding lines in the
plugin as I show you bellow:

I am attaching you the modified plugin file.
Plus, I must mention that I have not found any error using an OpenSUSE
Linux 10.x distribution compiling with gcc:
eh2cln:~/2.2.10/nessus-plugins/plugins/nessus_tcp_scanner # gcc --version
gcc (GCC) 4.1.0 (SUSE Linux)
Thank you in advance.
